SEECIFICATION forming part of Letters Patent No. 622,496, dated April 4,1899.

Application filed rm 24,1898. Serial No. 684,402. (No model.)

To all whom it may concern:

Be itknown' that I, FRANK KNOBELOCH, a citizen of the United States, anda resident of Dayton, in the county of Montgomery and State 'of Ohio,have invented certain new and. useful Improvements in Paper Boxes,ofwhich the following is" a full, clear, and exact description, referencebeing had to the accompanying drawings.

My invention relates to the construction of paper or pasteboard boxes orlids of the kind known as knockdown, and has for its object to provide aboxer lid formed from a single blank of cardboard or other suitablematerial and which may be easily brought or folded into shape, having atthe same time strength and rigidity, the nature of my improvements beingmore fully hereinafter set forth and described, and shown in theaccompanying drawings, which form part of this specification, in whichthe heavy lines indicate-the out portions of the blank and the dottedlines the scores or creases.

In the drawings, Figure 1 is a plan viewof a blank of cardboard or othersuitable material out and scored to be folded into shape and form myimproved box or lid. Fig; 2'is a perspective view of the box or lid inprocess of construction. Fig. 3 is a perspective view 'of the box or lidcomplete.

Like letters of reference indicate identical parts in all the figures.

A is the portion of the blank that forms the bottom, B B the portionsthat form the sides, and G O the ends. In order to form the box orlid,'the side flaps B are folded over at the score (1 onto the side B,where it is preferably glued in place in order to produce a ncaterappearance, though it need not be glued, if desired. The sides, composedof the side flaps B and the side B, are then folded up at right anglesto the bottom A, as shown in Fig. 2. Integral with the side flaps B areextensions 1; I), provided with slits 'e, which extensions are then bentin at right angles to the sides, asshown in Fig. 2. Intermediate thesides l3 and ends C are wings c c, which for pur-' poses of appearanceand that they may fold into place and at the same time have theiredge'flush with the edge of the extensions 1) b are cut in the mannershown in' Fig. 1. These wings are scored diagonally, as shown, to permaybe cut away from the end C, in which case it will not be necessary toscore it diagonally; but it may then be folded in at right" angles tothe sides in the same manner as the extensions 1) are folded in. I,however, prefer to leave it integral with the sides and ends and have itscored, as indicated, and fold into bellows folds, as with thisconstruction the corners, which are subject to considerable wear, aregreatly reinforced and strengthened. The ends 0' are provided with oneor more tongues 61, which register with and are inserted in the slits ein the extensions b, as

shown in Fig. 3. In order t0 facilitate the If desired, however, thewings-c suitablematerial, the combination with bottom, sides, and ends,of wings intermediate the sides and ends, and extensions integral withthe sides, said extensions provided with material, the combination withbottom, sides,

and ends, the sides and ends'scored 'to,. ;fold

upon themselves, of side extensions and wings integral with the sides,said extens ons and wings scored to fold in at right angles to the sidesand lie intermediate the overlapped portions of the end fiaps,,theoverlapping portion of the endsprovided with tongues register ng Joewith slits in the side extensions whereby the sides and ends are lockedin position, substantially as shown and described. 3. In a box orlid cutand scored from a single blank of cardboard or other suitable theoverlapping end flaps, said end flaps pro-V vided with tongues whichenter slits in the side extensions to lock the sides and ends in place,substantially as shown and described. 4. In a knockdown box or lid cutand scored I from a single blank of cardboard or other suitablemateriahthe. combination with bottom,

sides, and cnds,of side flaps having side extensions, said extensionshaying one or more slits, one or more tongues on 'the end flaps to beinsertedin said slits and lock the sides and ends in place,substantially as and in the manner described.

5. In a box or lid, cut and scored from a single blank of cardboard orother suitable material,the combination with bottom A,sides B, B, B, B,and ends 0, O, G, C, the sides B, B, and ends 0, C, scored to fold'uponthemselves, of side extensions 1), integral only with side flaps'B', andhaving slits e, and scored to fold in at right angles to the sides, and

tongues d, integral with the overlapping end a flaps C, said ton ues dregistering with the slits e, in the side extensions,substantially 35 asandin the manner described.
